The accompanying drawings, where like reference numerals refer to identical or functionally similar elements throughout the separate views, together with the detailed description below, are incorporated in and form part of the specification, and serve to further illustrate embodiments of concepts that include the claimed disclosure, and explain various principles and advantages of those embodiments.
The methods and systems disclosed herein have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
The present disclosure is now described more fully with reference to the accompanying drawings, in which example embodiments of the present disclosure are shown. The present disclosure may, however, be embodied in many different forms and should not be construed as necessarily being limited to the example embodiments set forth herein. Rather, these example embodiments are provided so that the disclosure is thorough and complete, and fully conveys the concepts of the present disclosure to those skilled in the art. Also, features described with respect to certain example embodiments may be combined in and/or with various other example embodiments. Different aspects and/or elements of example embodiments, as disclosed herein, may be combined in a similar manner. Further, at least some example embodiments may individually and/or collectively be components of a larger system, wherein other procedures may take precedence over and/or otherwise modify their application. Additionally, a number of steps may be required before, after, and/or concurrently with example embodiments, as disclosed herein. Note that any and/or all methods and/or processes, at least as disclosed herein, can be at least partially performed via at least one entity, at least as described herein, in any manner, irrespective of the at least one entity have any relationship to the subject matter of the present disclosure.
Generally described, the present disclosure describes aquaculture systems that include bottom grading features. In some embodiments, a plenum comprising a plurality of conduits is associated with an aquaculture vessel. In some embodiments, a multiway valve allows for selective use of a mortality container and/or a grading system.
In some embodiments, the aquaculture systems disclosed herein can comprise a means for selectively aligning an outlet (e.g., drain) of the vessel with outlet interfaces (e.g., conduits) of the plenum allows for bottom grading of deceased fish and recirculation of live fish.
These and other advantages of the present disclosure are provided in greater detail herein with reference to the collective drawings.
In operation, as fish are cultivated and grow in the aquaculture vessel 102, some fish may die. The deceased fish will fall to the bottom of the aquaculture vessel 102. The sloped configuration of the bottom surface 108 ensures that these deceased fish will be directed into the outlet 112. In another function, the sloped configuration of the bottom surface 108 ensures that live fish will aggregate near the outlet 112 when the fish are selected for either grading or harvesting. To be sure, the “harvesting” of fish can include any operation in which live fish are moved out of the aquaculture vessel 102, which can include moving the fish into another vessel or otherwise. Grading requires movement of the fish into a grading pipe through use of a valve, which is disclosed in greater detail infra.
The plenum 104 comprises a housing or enclosure 114. Two or more conduits, such as a mortality conduit 116 and a harvesting conduit 118 can be included in the plenum 104. Additional conduits can be utilized in some embodiments. A junction 120 is coupled to the outlet 112 of the aquaculture vessel 102. In some embodiments, the junction 120 is a j-shaped member having a nozzle end 121 that aligns with one or more of the various conduits of the plenum 104.
In some embodiments, the junction 120 can swivel to selectively align with the two or more conduits of the plenum 104. For example, the junction 120 can selectively align with each of the mortality conduit 116 and the harvesting conduit 118. To transmit the fish out of the aquaculture vessel 102, the junction 120 (e.g. a swiveling junction) can be aligned with the harvesting conduit 118 and fish can exit through the harvesting conduit 118 by way of the junction 120 (e.g. a swiveling junction).
In some embodiments, the outlet 112 has a funnel configuration or shape in area 122 that terminates at a connection to one end of the junction 120.
The aquaculture system 100 in some embodiments comprises a mortality pipe 124 that is a pathway of fluid communication between the mortality conduit 116 and the mortality container 106. In one embodiment, the mortality pipe has a first section that extends between the junction 120 and a multiway valve 126 (e.g. three-way valve) and a second section that extends between the multiway valve 126 and the mortality container 106. In some embodiments, the multiway valve 126 is located in-line with the mortality conduit 116.
The mortality container 106 comprises an enclosure that is in fluid communication with the mortality pipe 124. The mortality container 106 is fed from underneath by the mortality pipe 124 in some instances. In some embodiments, the mortality container 106 is accessible from an upper end so as to allow for removal of decease fish that are trapped inside the mortality container 106. In one or more embodiments, the mortality container 106 is positioned near an upper end of the aquaculture vessel 102.
In various embodiments, the mortality container 106 comprises a shunt 128 that extends into the aquaculture vessel 102. The shunt 128 allows live fish traveling through the mortality pipe 124 to re-enter the aquaculture vessel 102.
According to some embodiments, the mortality container 106 comprises a filter section output conduit 130. The filter section output conduit 130 allows for seawater in the mortality container 106 to be directed to one or more filtering assemblies for treatment.
In some embodiments, the multiway valve 126 is coupled with a grading pipe 134. In some instances, fish can be diverted through the grading pipe 134 for analysis when the multiway valve 126 is closed to the mortality container 106. In general, the multiway valve 126 comprises a first outlet that couples with the mortality container 106 and a second outlet that couples with the grading pipe 134.
In operation, when fish are being cultivated in the aquaculture vessel 102, the junction 120 (e.g. a swiveling junction) is aligned with the mortality conduit 116 and the multiway valve 126 is configured so that the grading pipe 134 is closed and the mortality pipe 124 is open. This configuration allows both live and dead fish to circulate through the mortality container 106. Deceased fish remain in the mortality container 106 and live fish can re-enter the aquaculture vessel 102 through the shunt 128 between the mortality container 106 and the aquaculture vessel 102.
It will be understood that as deceased fish remain in the mortality container 106, the deceased fish may give off contaminates that affect seawater quality. Thus, a pump can be used to draw seawater in the mortality container 106 into the filter section output conduit 130. The seawater can be cleaning using any number of cleaning techniques such as drum filtering, biofiltering, trickling, and so forth.
When grading of fish is desired, an operator or control system can be configured to switch the multiway valve 126 so that the grading pipe 134 is open and the mortality pipe 124 is closed. Live fish (and in some instances deceased fish) are directed through the grading pipe 134.
When an operator desires to grade a portion of the fish in the vessel, the method includes a step 308 of opening the grading pipe using the multiway valve, which closes the mortality pipe, to allow the fish to flow into the grading pipe.
The method can include allowing deceased and live fish to travel through a junction into mortality container by way of a mortality pipe extending between the mortality container and the mortality conduit. As noted above, the junction couples with a drain or outlet of the vessel. In some embodiments, the method includes grading the deceased fish according to accepted standards that would be known to one of skill in the art.
In some embodiments, the movement of fish and seawater through the aquaculture system is facilitated through the use of one or more pumps that push or pull water through the various components and pipes of the aquaculture system.
In some embodiments, the method can include selectively re-aligning the junction with a harvesting conduit, in embodiments where the junction comprises a swiveling junction.
